Last Tuesday, I woke up early. At 6h50 A.M., I had a meeting at Porte Maillot with my HEC EMBA Energy Major fellows to take a bus to Nogent-sur-Seine to visit EDF's nuclear power plant (NPP) in Nogent-sur-Seine.
- EDF runs 17 nuclear power plants in France, all of them pressurized water ractors.
- 89 % of EDF's energy mix in France consists of nuclear power.
- The most recent NPP is Flammanville and has adopted the EPR (European Pressurized Reactor) technology. Its construction costs account for 6 BEUR.
- 1st circuit: Inside the reactor, the nuclear fission heats pressurized water (155 bar) up to 2000° Celsius.
- 2nd circuit: Heated water of the first circuit generates steam in the second circuit. This steam drives a turbine that will generate electricity.
- 3rd circuit: The steam condensates and is then either reused or ejected in the air, via the cooling tower.
- Height of the cooling tower: 100 m
- Width of the concrete wall: 1.50 m on the bottom and 0.60 m on top
